RENAULT ISK RECOVERY SERVICE MD1CS006 EMS3160 SDI321 EMS3140 EMS3161 EMS3141 EMS3125 EMS3120 EMS3155 EMS3150 SID309 SID310 SID307 and others.
The service consists in calculating the ECU-derived 6-byte synchronisation code called ISK for the Renault immobiliser system communicating via the CAN bus.
Calculations are possible for all controllers ECU with a first-generation CAN immobiliser system implemented by around 2020.
Although the calculation is possible for all ECUs, it is most necessary for ECUs using the HSM hardware security module for data transfer and decryption, as reading the ECU contents does not allow the ISK values in the eeprom and flash areas to be found anyway.
Pictured is one option for collecting the relevant data, I have written a special logger for data collection that works with the very popular Tactrix Openport 2.0 interface, the programme is available free of charge, the ISK calculation is payable.
The software is protected by a packer. Use the provided SHA-1 hash (89716313d851bb789c80859b074d5e337df5d1df) to set an antivirus exception and validate the executable.
To collect the data, connect the ECU on the table according to the diagrams available for the vehicle it came from.
We then connect the Openport interface to the power supply and the CAN lines from pins 6 and 14 of the interface to the CAN data line of the engine controller we are working on.
When everything is connected, press the START LOGGING button in the logger programme.
Information is collected when the power to this ECU is cycled on and off, the number of cycles is set to 9.
When the programme has collected enough information, it will display it and issue a message to complete the logging process.
The calculation is based on the collected CAN query meta data from the ECU to which we want to retrieve the synchronisation code called ISK.
The data collected must be saved and sent to us and we will calculate the ISK code on its basis.
Thanks to the recovery the ISK synchronisation code, the UNICAN emulator can be used to unlock the ECU.
If you are an EU-based automotive electronics company, you can send us an ECU unit for ISK code recovery service – please contact us or to one of My distributors .
In order to use this solution, the customer must be qualified as an automotive electronics technician and have the necessary diagnostic tools and wiring diagrams.
In the event of problems and the need for technical support, a CAN bus analyzer will be required in addition to the ECU files, as well as the ability to operate it.
